N Field Observations

Palmer amaranth has evolved resistance to number of foliar active herbicides. This project was designed to evaluate if residual herbicides applied pre-emergence as well as post-emergence can provide season-long control of Palmer amaranth in soybean. Ankit Yadav, a PhD student, discusses row spacing with herbicides. #NFieldObs #NebExt @AmitUNL @AnkitUNL @MarthaMamo3 @unlagrohort @UNLExtension

Hairy vetch is an important legume cover crop that can convert atmospheric nitrogen into nitrogen that can be used by grass crops such as popcorn. It can also suppress weeds and provide nitrogen; however, terminating hairy vetch is important. Sai Suvidh Maddela is a PhD student speaking in video. #NFieldObs #NebExt @AmitUNL @SuvidhUNL @MarthaMamo3 @unlagrohort @UNLExtension

Palmer amaranth has evolved resistance to several foliar-applied #herbicides, making it one of the toughest weeds in #sorghum production. This research evaluated whether residual herbicides applied pre- and post-emergence can deliver season-long Palmer amaranth control and improve weed management. @AmitUNL @unlagrohort @SuvidhUNL #NFieldObs

Weed control programs from multiple companies were compared during the 2026 Weed Management Field Day in late June, providing a firsthand look at their field performance. #NFieldsObs @AmitUNL @MarthaMamo3 @unlagrohort @UNLExtension @UNL_IANR

Hairy vetch is a valuable legume cover crop that captures nitrogen from the air and makes it available for crops like popcorn. It also helps suppress weeds and adds nitrogen to the soil. Proper termination, however, is key to maximizing its benefits. @AmitUNL @unlagrohort @UNLExtension @SuvidhUNL #NFieldObs #NebEx

We're evaluating the Ecorobotix ARA precision sprayer for targeted weed control in soybean. By detecting weeds in real time, it sprays herbicide only where needed, reducing chemical use. UNL Weed Management Specialist Amit Jhala and Crop Care Manager Katarina Lee explain. @AmitUNL @MarthaMamo3 @unlagrohort @UNLExtension @UNL_CropWatch #NFieldObs #

Extension Entomologist Justin McMechan scouts for #Soybean Gall Midge in the field, discussing symptoms and treatment resources. @justinmcmechan #NebExt #NFieldObs

Pending registration, Rapidicil, a new PPO-inhibiting, post-emergence burndown herbicide, can provide effective control of winter weeds. Research is being conducted at UNL indicates adjuvants can affect the efficacy of Rapidicil. @AmitUNL @AnkitUNL @MarthaMamo3 @unlagrohort

Early-season weed scouting is key to effective corn weed management. Identifying weeds like Palmer amaranth early helps guide herbicide selection, application timing, and any additional control needed. @AmitUNL @AnkitUNL #NebExt #NFieldObs @unlagrohort

Hail and wet weather in some parts of the state during June have contributed to the growth of Bacterial Blight and Frogeye Leaf Spot in #soybeans. Extension Soybean Pathologist Dylan Mangel explains what to look for and how to develop a treatment plan. @DylanMangel @UNL_CropWatch #NebExt #NFieldObs
